The place he's talking about is called http://www.audible.com
He actually says "audiblepodcast.com/pod101", but when I googled it, it took me to audible.com.
It looks like you can sign up for a 14-day free trial, and you can download 1 book free. The information is on the Home Page.
I went in, clicked on "Browse Audio" up near the top of the page, then entered "Japanese" into the search box. It came up with 74 books, including some by Pimsleur, which Peter had mentioned.
Hope this helps!
